Bio‐Inspired Molecular Events in Poly(Ionic Liquids)

Advanced Functional Materials, EarlyView.
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Macroscopically uniform interface layer with Li+ conductive channels for high-performance Li metal batteries

Nature Communications
The numerous grainboundaries solid electrolyte interface, whether naturally occurring or artificially designed, leads to non-uniform Li metal deposition and consequently results in poor full-battery performance.

High Energy Density Asymmetric Aqueous Supercapacitor Based on a 2D Manganese Carbide as a Positive Electrode

Advanced Functional Materials, EarlyView.
A circular route, involving upcycling of waste surgical masks, affords a Mn‐based layered carbide with porosity, redox activity and low work function. These features enable its effective operation as positive supercapacitor electrode in an aqueous asymmetric supercapacitor delivering 213 Wh L−1 energy density.

Bioinspired Polypeptide Dendrimer‐Modified Thin‐Film Composite Membranes for Selective Lithium‐Magnesium Separation with DFT Insights

Advanced Functional Materials, EarlyView.
We fabricated a biomimetic dendrimer‐modified thin‐film nanocomposite membrane with a coordination‐assisted ion‐selective interface. pH‐responsive polypeptide sites preferentially bind Mg2+ and promote Li+ permeation, as predicted by density functional theory calculations of metal‐ligand interactions.

Where Most Frameworks Degrade: Flexible Bimetallic Phosphonate Crystals as pH‐Universal Supercapacitor Electrodes

Advanced Functional Materials, EarlyView.
Plastically flexible single crystals of the bimetallic phosphonate framework [Cu(2,2′‐bpy)VO(O3PC6H5)2] combine mechanical adaptability with robust pseudocapacitive charge storage. The material delivers about 140 Fg−1 at pH 4 and pH 10 and remains stable across pH 2‐12, enabling energy storage under comparatively mild electrolyte conditions.
